DAVID G. JOSEPH, OF MARTINS FERRY, OHIO, DAVID DUMMER, F WHEELIN G, WEST VIRGINIA, AND EVAN J. I-IOLLEY, 0F MARTINS FERRY, OHIO.

' nornromsnme APPARATUS.

To all whom it may concern:

Be it known that we, Davin G. JOSEPH, a subject of the King of England, and a resident of Martins Ferry, county of Belmont, and State of Ohio, DAVID DUMMER, a citizen of the United States of America, and a resident of Warwood, Wheeling, county of Ohio, and State of West Virginia, and .EVAN J. HOLLEY, a citizen of the United States of America, and 'a resident of Martins Ferry, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Roll-Polishing Apparatus,

of which the following is a specification.

I This invention relates broadly to roll polinvention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully explained, reference being had to the accompanying drawings, in which- Figure 1 a transverse section of the invention applied to a set of rolls; Fig. 2 is an enlarged top plan view of the abrading blocks and the carrying means therefor;

Fig.3 is a front elevation of thesame; Fig. 4 is a transverse section on the line M, Fig. 3; Fig. 5 is an enlarged front elevation of the pivoted bar-hanger; Fig. 6 is an enlarged partial sectional view of the tension adjusting means for the bar; and-Fig. 7

of the head portion of a is a detail view lever."

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views, 1 andv 2 indii cate the upper and lower rolls, respectively, of a rolling mill, and 3' a housing in which said rolls are mounted. Pivotally mounted at a suitable pointbn each housing adjacent to the up or roll 1 is a vertically disposed hen er 4 aving a headed wrist pin 5 adapted or pivotally su porting thereon a lever 6 of suitably curve form, said lever ha vi mg a head portion? whichis normally held in serving to I Specification of Letters Patent. J Patented Nov, 14, 1916. Application filed July 1, 1916. Serial No. 107,184. I i

a position closely adjacent to said upper roll at a point below a horizontal plane passed through the axis of the latter. The heads 7 of the companion levers 6 are designed to receive thereon in firmly seated position the oppositeends of a bar 8 which is substantially L-shaped .in cross section, as shown in Fig. 4, said bar having formed on its under side adjacent to each end ,alug 9 adapted to seat in a recess 10 provided therefor in each head and also having formed integral therewith a rearwardly directed longitudinally disposed flange 11 of hook shape adapted to engage'with a lip 12 formed on each head, as shown in Fig. 1, said lugs 9 and flange 11 interlock the bar 8 with said he d "A forwardly projecting arm 13 is formed on theupper part of the bar 8 adjacent to each of its ends, and directed downward through said arm is a set screw 14 designed to have its point seat upon the top of a wedge-like retaining bar15 which rests upon and binds in place a plurality of alined blocks 16 of a suitable abradant, as emery stone, which are mounted upon the substantially horizontalportion of said bar 8. The rear faces of said blocks rest against the front face of a flexible bar 17 :which rests upon said horizontal portion and which is yieldingly held in an advanced positionby a plurality of suitably alined springs, as the bowed sprins 18 which. have one; end fixed to said bar 1 and have their backs or bowed portions disposed adjacent to the upright portion of-th'e bar 8. Adjusting screws 19 8 have their points disposed against said springs 18 and are adapted for adjustment to regulate the tension ofthe latter. 'Said adjusting screws 19 underlie and are protected by the flange 11.

" directed through said upright portion of bar The engaging faces of the blocks 16 and block-retainmg-bar 15 are similarly inclined I so that while the letter positively prevents the former. ,from bein advanced beyond a definite point, rearward movement of the blocks against the tension of the springs 18 is not thereby. unduly retarded' .The 'blocksproject forward a suitable distance beyond the jaw-like vise in which they under yielding pressure exerted y suitable tensioningnieans connected to the outer end are mo'unted, as aforesaid, :and. have their front edges frictionally engagin the roll 1 with which the block-holding jaw is thruste forward may be regulated by adjustment of the tension of the springs '20, which is accomplished by manipulation of the turnbuckles 22.

In practice, the blocks separately yield to conform to inequalities in the surface of the roll 1. Thus is avoided the objection to the employment of a single bar of the full length of the roll nstead of the short blocks 16, it being apparent that depressions in the rolls due to unequal wear would notbe engaged by such bar.

Being pivotally supported, the hangers 4 obviously permit the levers supported thereby to swing inward and outward with respect to the axis of the engaged roll.

For maintaining the polished condition of the lower roll 2, the latter is engaged by apparatus substantially-similar to that here: inbefore described located on the opposite side of the mill. In said similar apparatus, the blocks 16 engage the roll below a horizontal plane passed through said roll, and the lever B has its outer end curved in a. direction reverse to the curvature of the corresponding end of lever 6.

As is apparent, when it is desired to removethe apparatus to an out-of-the-way position with respect to the rolls, the bar 8 with its associated parts may be lifted from the head-portions 7 of the levers 6, whereupon the latter may be lifted from the hangers 4 and detached from'the ring 23 of the tensioning means.

In order to prevent the formation of annular ribs on the surfaces of the rolls due to the slight intervening spaces between adjacent blocks 16, the latter maybe slightly adjusted laterally from time totime so that wear of-all parts of the surfaces of the rolls will be substantially uniform.

lVhat is claimed is 1. A roll-polishing device comprising oscillatory hangers carried by the roll housings, a pair of levers fulcrumed on said hangers, said levers being unconnected and having head portions, a bar having its end reinovably mounted upon and interlocked with said head portions, a plurality of alined roll-polishing blocks carried by said bar, and resilient means connected to the outer end of copies of this patent may be obtained for in cents each, by name the each of said levers whereby the latter are caused to yieldingly present said blocks to the surface of a roll.

2. A roll-polishing device comprising a hanger pivotally mounted upon each of the roll housings and adapted for oscillatory movement toward and away from a roll, a

lever pivotally mounted upon each of said hangers, a bar having its ends removably mounted upon and interlocked with the head portions, a plurality of alinedroll-polishing blocks carried by said bar, resilient means connected to the outer ends of said levers whereby the latter are caused to yieldingly thrust said bar forward for presenting said blocks to the surface of the roll, and means carried by said bar whereby said blocks are rendered separately yieldable.

3. A roll-polishing device comprising a pair of levers. located adjacent to the opposite roll housings, oscillatory hangers carried by said housings and constituting fulcrums upon which said levers are pivotally supported, said hangers permitting said levers to swing forward and back with respect to a roll, said levers having head portions at the inner ends thereof embodying a lip and a recess, a bar having its ends adapted for removably interlocking with said head portions, each of said ends having portions for interengaging the lips and recesses of said head portions, a plurality of alined roll-polishing blocks carried by said bar, and resilient means connected to the outer ends of said levers whereby the latter are caused to yieldingly present said blocks to the surface of said roll.

at. In a roll-polishing apparatus, a lever pivotall supported by each roll housing, said lever having a head portion embodying an upwardly and rearwardly directed lip and provided with a recess below and in front of said lip, a bar having ends adapted for removably interlocking with said head portions, each of said ends having a lug -for seating in the recess of such head portion and having a hook-like flange for engaging the lip of such head portion, roll-polishing blocks carried by said bar, and means associated with said levers whereby the latter are a vrated to yieldingly press said blocks to the surface of the rolls.

In testimony whereof we aflix our signatures in presence of two witnesses.
